Strings from Loop to array

Hey,
I have the following loop:
for i=1:Parameter1
for j=1:Parameter2
Name=['Name_' int2str(i) '_' int2str(j)];
end
end
I want all the Names writen in one array with one column. Means a total of i*j rows.
How can I write this array?
Would appreciate some help!

Note: Star Strider's answer using COMPOSE (as dpb suggested) is simpler and more efficient than using loops.

Yeah, but you don't even need compose here with the new string class --
[I J]=meshgrid(1:3,1:3);
>> Names=string("Name_"+I+"_"+J)
Names =
3×3 string array
"Name_1_1" "Name_2_1" "Name_3_1"
"Name_1_2" "Name_2_2" "Name_3_2"
"Name_1_3" "Name_2_3" "Name_3_3"
>>
letting meshgrid deal with the implicit loop structure. There might even be a way with the new implicit expansion syntax although I've yet to fully grasp when/where it comes into play...let's see what happens if--
>> N1=3;N2=4;
>> string("Name_"+[1:N1]+"_"+[1:N2].')
ans =
4×3 string array
"Name_1_1" "Name_2_1" "Name_3_1"
"Name_1_2" "Name_2_2" "Name_3_2"
"Name_1_3" "Name_2_3" "Name_3_3"
"Name_1_4" "Name_2_4" "Name_3_4"
>>
and "Yes, Virginia, there is a Santa Claus!" :)

Parameter1 = 5 ;
Parameter2 = 5 ;
Name = cell(Parameter1,Parameter2) ;
for i=1:Parameter1
for j=1:Parameter2
Name{i,j}=['Name_' int2str(i) '_' int2str(j)];
end
end
Name
